250 messages ago in this thread alone, and in several other now
fortunately extinct threads, I asked "jim beam" to provide us with
proof of his competence by either:

a) proving his claim that it is impossible for a steel bike to be
lighter than a similarly equipped aluminium bike (the examples were my
one steel and two ali touring/commuter/utility bikes), or

b) telling us what he has ever built with materials that would give
his claims of expertise credibility (I mentioned by way of example a
68ft racing yacht I designed and built as a moulded wood monocoque 40
years ago -- but I would have been happy to accept a far lesser
example as proof of competence from the anonymous "jim beam", say a
load-bearing automobile chassis in reinforced plastic)

"jim beam" responded by

a) *not* answering either question above and

b) instead trying to set me exam question on matters on which I've
published a textbook (his questions made clear he hadn't read the book
either). It promptly turned out that "jim beam" has as little
credibility on combustion engines, internal or external, of any cycle,
with any valve operating mechanism, as he has on materials. Zero.

Several other parties have tried valiantly and patiently to extract
sense or proof from "jim beam" but still he stonewalls and instead
demands "credentials" from anyone who questions him. A summary of that
sorry tale can be read below.

Perhaps it is time to give up on that worthless little man "jim beam".
I have.

really andre? why are you still tracking this thread then? and you're
top posting - you only do that when you're having another emotional
"episode".

bottom line, you ignorant narcissistic fraudster, and ignoring your
other fantastic "engineering" fantasies, is that you made a claim that
your steel frame is 10lbs lighter than your aluminum frame of the same
design. and you've signally failed, despite numerous requests, to back
that statement up. given the facts of the material, and that if you
actually had evidence, it would be so easy to provide, the inescapable
conclusion is that you're bull****ting. not much of a platform from
which to bleat about trying to be "holier than thou".
